SPECIFICATION forming part of Letters latent No. 411,259, dated September 17, 1889.

Application filed April 19, 1889. fierial No. 307,802. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE \V. RITTERS- BAcH,a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Railroad-Ohairs,which improvement is fully set forth in the following specification and accompanying drawings.

My invention consists of a railroad-chair having a movable cheek-piece which may be tightened against the rail and firmly held, the construction of parts being hereinafter fully set forth and definitely claimed.

Figure 1 represents a side elevation of a railroad-chair embodying my invention. Fig. 2 represents a top or plan view thereof. Fig. 3 represents a perspective view thereof on a reduced scale, the parts being in different position from those shown in Figs. 1 and 2.

Similar letters of reference indicate corresponding parts in the several figures.

Referring to the drawings, A designates the bed or base of the chair, having the stationary cheek-piece B and the movable cheekpiece O, the latter being seated in a transverse groove in the guiding-piece D, which rises from the baseA and is fitted thereto by a dovetailed joint, so as to slide toward and from the rail in a direction at a right angle thereto. Rising from the side of the base adjacent to the piece D is a shoulder E, which has between it and said guiding-piece D a channel or key-seat F, which extends inthe longitudinal direction of the chair, and receives a dovetail key G, of tapering or wedging form, it being noticed that the back or outer end of the movable cheek-piece enters said seat F and forms with the opposite wall thereof a dovetail for the key G.

In order to prevent the rail from slipping, the same is formed with a slot or recess to receive a tongue H on the movable cheek-piece.

The operation is as follows: The key is withdrawn and the movable cheek-piece run back, as will be seen in Fig. The rail is now located on the base and the flange of one side inserted underthe cheek-piece B. The checkpiece 0 is then advanced and the key intro duced into the seat F, and as itengages with the back of said cheek-piece and opposite wall movable cheek-piece also by a dovetailed joint, it is evident that said cheek-piece and key are prevented from rising and consequent vertical displacement, and thus the parts reliably retain their positions.

When the key is withdrawn, the movable cheek-piece may be run back and the rail and chair then disconnected.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A railroad-ch air having a movable cheekpiece, and a key which engages with said piece, said key being connected with said cheek-piece and a shoulder on the base by a dovetailed joint, and said cheek-piece being also connected with its guide by a dovetailed joint, the parts being combined substantially as described.

2. A railroad-chair having a base with a stationary cheek-piece,a guiding-piece and a shoulder rising therefrom, a movable cheekpiece with tongue adapted to engage in a recess in the rail, and a key adapted to bear against the movable cheek-piece, said parts being combined substantially as described.

3. A railroad-chair consisting of a base part having a stationary cheek-piece, a guidingpiece and a shoulder, the said guiding-piece having a transverse groove with inclined walls, a movable cheek-piece working in said groove and having a lip on one end, a tapering key in the channel between the shoulder and guiding-piece, said parts being combined substantially as described.
